Junior attackman Sean Tyrrell (Calgary, Alta.) and junior midfielder Keenan Koswin (Winnipeg, Man.) each posted a career-high five points to lead the UMass Lowell Men's Lacrosse team to a 18-13 victory against Siena on Saturday afternoon at Cushing Field Complex. The River Hawks, who improved to 1-2 overall on the season, set a Div. I program record with 18 goals in the contest, shattering the previous record of 12 which happened on two occasions last season. Siena drops to 0-4 overall with the loss. It marks the first win for the River Hawks against Siena in three all-time meetings. "I thought the game started out pretty slow, Siena is a well coached team, they are very potent offensively," said Head Coach Ed Stephenson. "I really respect that the guys gathered themselves in the second half and sometimes it takes a couple guys to get the momentum going, I thought our faceoff crew really got the momentum going in the second half." Koswin's hat trick was the first of his career, while Tyrrell recorded two goals and three assists. Tyrrell, Austin Lane (Aurora, Ont.), Sam Klingsporn (Aloha, Ore.) and Jon Phillips (Delta, B.C.) all registered a team-high five shots. Siena led at halftime, 6-4, but UMass Lowell went on to score 14 second-half goals to seal the victory for the River Hawks. UMass Lowell amassed 43 shots in the game with 30 of them coming in the second half of action. Freshman Brett Dattilo (Derry, N.H.) had an impressive day, tallying his first career goal in the fourth quarter, winning 23 of 33 (70%) faceoffs and posting a team-high nine groundballs. Sophomore goaltender Grant Lardieri (Ada, Mich.) tallied a career-high and school record 19 saves, which included 11 second-half stops against Siena. Lardieri's previous career-high was 17 saves, which he set last week against Harvard. The River Hawks went 2-for-5 on man up opportunities. Siena's Chris Robertson totaled a game-high five goals in the losing effort for the Saints. Aaron Lewis made 12 saves, allowing 18 goals for Siena.
